This lib allows you to build and write an Excel file dynamically, it does not include any reader capabilities making the library super lightweight.
Visit the Live demo to get started and see all available options and methods that the library offers.
You can also take a look at the "Used by" section below to see real world applications taking advantage of this library.
Excel-Builder-Vanilla is a fork of the popular excel-builder.js project (thanks to @stephenliberty for this great library). The main goal of creating this fork was to modernize the project by removing old dependencies that are no longer necessary and also replace JSZip by fflate which provides an ESM build and is indirectly giving us better Tree Shaking. The other goal was also to provide an ESM build to eventually get away from CommonJS (CJS bundle is still offered but we strongly suggest that you migrate to the ESM approach)
The modernization steps:
- migrate to TypeScript (which is giving us TS Types
d.ts) - drop
Qdependency (we now simply use nativePromise) - drop
Lodashdependency (we now use native JS code) - replace
JSZipdependency withfflatewhich has an ESM build and offers better performance. - bump version to
v3.0.0as amajorrelease (the original project version was in the2.xrange.)- note that the changelog did not exists prior to
v3.0.0
- note that the changelog did not exists prior to
The project now requires only 1 dependency which is fflate.
This modernization is providing a huge decrease in the final build size, with only 1 dependency, and also offers better performance 🚀
npm install excel-builder-vanillaThe project offers 3 different build types, choose the best one depending on your use case
- ESM: to
import from(preferred) - CJS: CommonJS to support old NodeJS
require()- will probably be dropped in the future - IIFE: standalone script which provides
ExcelBuilderon thewindowobject
// ESM (preferred) - npm install
import { createWorksheet } from 'excel-builder-vanilla';
// CJS - npm install
const { createWorksheet } = require('excel-builder-vanilla');
// IIFE - CDN
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/excel-builder.iife.js"></script>
<script>
const worksheet = ExcelBuilder.createWorksheet(); // or window.ExcelBuilder.createWorksheet();
</script>Please note that since we use fflate (which creates and compresses the Excel file before sending it to the browser), you might get some CSP errors because of its use of Web Workers. For that reason, you might need to adjust your CSP rules by adding worker-src 'self' blob:;
<meta http-equiv="Content-Security-Policy"
content="default-src 'self';
// other rules...
worker-src 'self' blob:;" />This fork was created mostly to support Tree Shaking (ESM), to get away from CJS, to provide TS Types and finally to update all project dependencies. It is used by a few other Open Source libraries that I also maintain and require Excel export:
Pull Request are welcome, feel free to contribute.
If you wish to contribute to the project, please follow the steps below:
Note: this project uses pnpm workspaces, you can install pnpm by following their installation or use NodeJS corepack enable to run any of the pnpm scripts shown below:
- clone the lib:
git clone https://github.com/ghiscoding/excel-builder-vanilla
- install it with pnpm from the project root:
pnpm installORnpx pnpm install
- run a full TypeScript build
pnpm run buildORnpx pnpm run build
- run in development mode (lib & demo)
pnpm run devORnpx pnpm run dev
Before submitting a PR (pull request), please make sure that you followed these steps for a better chance of a successfull PR:
- make sure that you have already executed
pnpm install - run the Biome lint npm script (or simply use step 4)
pnpm run biome:lint:write
- run the Biome code formatting npm script (or simply use step 4)
pnpm run biome:format:write
- run a full Build (this will also run Biome lint/format, so you could skip step 2)
pnpm run build
